To all 'whom t may comme.:

Be it lmown that l, ABRAHAM ql'. Gunner, e citizen ot the United States, residin et Brooklyn in the county of Kings und tete of New York, heve invented new und usetul improvements in Autometic Ges Cut- S, of which the following is e specilicetion.

This invention reletes to automatic ges l@ cut-ods end one of the principal objects is troduce e device othis neture which s 'not be objectionebly bulky or uny sightly.

Another object is to produce e device of M this neture which shell be simple in construction, cheep to manufacture end e@- cient for the purpose for which it is designed.

Another object is to construct e device 2@ ol this nature of such ports endin such manner thet it will not easily get out ot order.

With these end incidental objects in view, the invention consists in certein novel construction end combinationV und errunge- -ments oi perts, the essentiel lectures of which ere fully set forth in the following description end cleim` end illustrated in the eccompening drewing comprising one 3@ sheet, in whic Y Figure l is e side `View pertly in .section ol my improved device etteched to e ges burner und showing the position essuined -by the verious puits when the ges is lightedu ne. Figure 2 is e, similer view showing the position which the ports essume when `the deine is extinguished.

.This invention contemple the provisionot e setety ges f w: or cuts@ malins whereby the dow of will be eutorneticnlly interrupted upon extinguishing the 1deins, end yet shell be compnet und cepeble ci being menulectured vet e very reesoneble rete.. z

. Referring more perticulerly to the drewings, l represents en ordinery ges burner end 2 the tip thereof. The burner is drilled horizontelly end through the epertures thus formed is pessed e. vulve c linder 3, prol@ vided with two verticelly eligned e ertures d end 5. The'memher 3 is provide et one end with e closure 6 heving e central eperi ture :forming e beering for e plunger rod 7. Rod 'l' is |provided with two collars or enlarged portions 8 und 9 between which is dened e spece 10. Members 8 end 9 are e snug lit for the bore of member 3, und member 9 noi-mollyA extends slightly from the open end of member 3' es shown 1n Figure 2, e coil spring 1l tending constantly to force the rod 7 in that direction by beering egeinst member 8. A limit of movement is set by e .heed l2 formed on rod I7. Normally the rod 7 is positioned with member 8 closing both epertures 4 end 5.

Secured to the top'ol the burner is e member 13 in which edepending rod 14 is edjustebly secured by means of u set screw 15. The lower portion of rod ll posses through en aperture in the upper portion of member 3 und has its ends errenged in sliding contact with member 9. Drilled in the side well oi the burner l is e small bleed hole 16 which is located opposite pin M end above which en aperture 17 is formed in the member 11.3.

ln operation, when the ges is to be lighted, the member 9 is pressed in level with the end ot member 3, which brings aperture 10 into .register with epertures t end 5 end permits e dow of gas tothe tip 2 where it is lighted, the ges from bleed hole i6 being lighted et the seme time. The smell jet et i6 will cause the thermostatic pin to expend so thet its lower end will bind egeinst member il und hold the seme end rod 7 egeinst the tension et spring l1. lt the ges vis blown out, pin M will conltrect end permit spring ll to move the y perte to the position shown in Figure 2 withl the member 8 shutting ed the dowv ot ges.

li' the lerge heme should be extinguished without extinguishing the smell deine, then the smell demo would serve es e pilot to re-light the -lerge deine through aperture 17.

Whitt is cleimed es new is:-

A vulve end burner structure including e vulve cesing having en aperture, e' burner in communication with seid eperture,l e bleed opening in seid burner, e, vulve plug movable in the well of seid cesing und e thernielly actuated rod located et one side lil@ of the burner and having one end freely extending Iinto the valve vcasing; and positioned with respect to the plug vso as to positively and directly bind same against move- `5 ment in the wall of seid"'casing on expansion of seid thermal means, a; manually controlled portion on the plug 'end resilient means for moving; the plug to e closed position with respect to said aperture on contraction of 'said thermally actuated means.` 10
